CLOTHES WRINGER.

Specification of Letters Patent; Patented June fi,

Application filed February'7,'1920,- Serial No.-357,053." Renewedbecember 14, 1921. Serial No 522,442.

To all whom it may concern:

Be it known. that I, WILLIAM HENRY MEYER, a citizen of the UnitedStates of America, a resident ofthe'city of St. Louis, in the'State of Missouri, have invented certain new and useful Improvements in Clothes \Vringers, of which the followin'g is a full, clear, and exact description, reference being had torthe accompanying drawings,

forming a part of'this specification.

This invention relates to improvements in.

clothes wringers, the main object beingto produce a strong and simple wringerstructure provided with a simple releasing device whereby the pressure at the wringer rolls may be easily and quickly released.

Fig. I is a front elevation, partly in section, illustrating a wringer embodying the features of this invention.

Fig. II is a vertical section taken approximately on the line II--II of Fig. I.

To illustrate the invention I have shown a wringer frame comprising upright end members 1 forming housings for the bearings 2 and 2' in which the wringer rolls 3 and 3 are rotatably mounted, said rolls being provided at their ends with journals engaging the bearings 2 and 2' respectively. The wringer frame also includes horizontally disposed upper members 4 integrally connected to the upright members 1.

Compression springs 5 are interposed between the upper bearings 2 and a tie-bar 6. Screws 7, acting upon end portionsof the tie-bar 6, may be adjusted to vary the pressure of the springs 5. These springs allow the upper roll 3 to move toward .and away from the lower roll and they tend to force the upper roll into engagement with the lower roll.

To illustrate the preferred form of the invention I have shown a thrust-receiving bar 8 arranged between the rigid frame mem bers 4 and located immediately above the tie-bar 6. Nuts 9 are secured to the end portions of the thrust-receiving bar 8 to receive the adjusting screws 7. It will now be understood that the spring pressure is transmitted through the end portions of tie-bar 6 to the lower portions of screws 7 and thence to the nuts 9 in the thrust-receiving bar 8. If the bar 8 is held in a fixed position, the springs 5 will be retained under pressure, and the screws 7 may be adjusted to vary the pressure. However, if the thrust-receiving bar. 8 is released, and permitted to move vertically, the spring pressure-willbe immediately relieved, and the upper wringer r0113 can "then be'freely moved -away from the lower roll. I p

I "will now describe the breakable bridge which engages the top face ofthe-thrust-receiving bar -8to normally retain said bar in a fixed position; This bridge preferably comprisesapairof abutment wings 10 and 10 located between the upper: frame niembers 4 and'ipivotally connected to th'e upper margins thereof as shown at-11, said frame members 4 being slotted to receive pivot loops which extend from the wings 10 and 10, and the pivots being approximatelyparallel with the axes of the wringer rolls. Each wing 10 and 10 is approximately L shaped in cross-section to provide a horizontal abutment face engaged by the thrustreceiving bar 8 and an upwardly extending retain the lever in the position shown in the drawings.

The clip formed by the releasing lever cooperates with the wings 10 and 10' to form a transverse bridge which extends across the upper portion of the wringer frame. This bridge is normally subjected to the spring pressure which tends to throw the thrust-receiving bar 8 in an upward direction; .To break the bridge, it is only necessary to depress the operating member '15 (Fig; I) thereby releasing the tongue 14 from the wing 10. In this event, the pressure transmitted through the thrust-receiving bar 8 will cause the wings 10 and 10 to turn on their pivots, so as to release the thrust-receiving bar 8,whereupon, thebar 8 will be thrown vertically to relieve the pressure of the springs.

I claim:

1. In a wringer, a frame, a pair of wringer rolls, yielding means for forcing one of said rolls toward the other, a movable thrust-receiving member subjected to the pressure of said yielding means, and a breakable bridge spanning said frame and cooperating with said movable thrust-receiving member to retain said yielding means under pressure, said breakable bridge comprising wings, pivots connecting the outer margins of said wings to said frame, the axes of said pivots being approximately parallel with the axes of said rolls, and a clip detachably connecting the inner margins of said wings, said clip being pivoted to one of said wingsand movable to disconnect the innermargins of said, wings. a a i 1 2. In a wringer, a frame, a pairxof wringer rolls, yielding means for forcing one of said rolls toward the other, amovable thrust-receiving member subjected to the pressure oi said ylelding means, and a breakable bridge spanning said frame and cooperating with said movable thrust-receiving member to retain said yielding means under pressure, said breakable bridge, comprising a pair iof wings, pivots connecting said wings to said frame, the axes of saidpivotsbeing approxiof said yielding means, and a breakable bridge spanning said frame and cooperating with said movable thrust receiving member to retain said yielding meansunder pressure, said breakable bridge comprising a pair of wings, pivots whereby theouter margins of said wings are attached to said vframe, the

axes of said pivots being approximately pars allel with the axes ofxsaid ro1ls, -said wings having upturned flanges facingieach other, and a clipcomprising a lever pivotedto one of saidfianges and overlapping the other flange", i a
